[web2py] LOAD component inside component

[Richard]

Hello,

I create a page with multiple components inside of it (the index page is basically an empty shell for the components)... But one of there is a form in one of the embed component which as a field with a widget that trigger modal form allowing to insert a value in another table and select this inserted value (something like SELECT_OR_ADD() would do). The problem is that my form embeded in the modal which the widget append to the page with LOAD() don't load... It hang on "loading..."

Any idea?

Is it even possible to trigger a LOAD inside a LOAD?

Thanks

Richard

Never tried. My guess is that 

jQuery.web2py.trap_form is not called for the inner forms.

If you call it manually using jQuery you can make it work.

But I would not. I would figure out how to use ractive.js instead.

[Richard Vézina]

Yes I should give it a real try, though I found usage example scarce after tutorial...

I need to improve my ractive skill

:)

simple use *.html view - not *.load

and use URL for set controller/function in LOAD()

I not use same views - onlu generic.html by:

def load_func_2():

   h = CAT()

   h += LOAD(...)

...

return h

def load_func():

...

   h = CAT()

   h += LOAD(URL('contloller','load_func_2', args=[], vars={}), ....)

return dict(h =DIV(h, _class='row'))

before to reload a sub-LOAD need stop it auto-loading - for preventing from double loads of sub-LOAD component

full script:

def remake_reload_script(tag, timeout=None): # tag = '#show_2'

    return '''

        var jelement = $("%s");

        var element = jelement.get(0);

        var statement = "jQuery('%s').get(0).reload();";

        clearInterval(element.timing); // stop auto-reloading

        ''' % (tag, tag) + \

        (timeout and '''

        element.timeout = %s000;

        element.timing = setInterval(statement, %s000); // start reloading

        ''' % (timeout, timeout) or '')

        

response.js = remake_reload_script('#show_1', 3)

Does this replace the reload() function that was in your post from Sunday? (Shown quoted below)

/dps

 

[Dmitry Ermolaev]

yes

instead:
    response.js +=  "jQuery('#show_2').get(0).reload();"

use 
      response.js +=  remake_reload_script('#show_2', 3)
